Description

Germanium70 is a high-purity, stable isotope of the metalloid element germanium, specifically enriched in the Ge-70 isotope. This material is critical for advanced research and development in fields requiring precise atomic-level control and minimal isotopic interference. It is primarily utilized by the semiconductor industry, national research laboratories, and academic institutions for applications in nuclear physics, detector calibration, and next-generation electronic materials.

Application

• As a target material for the production of Gallium-68 (68Ga) via proton irradiation, a key positron-emitting isotope for medical PET imaging.
• In the manufacturing and calibration of high-purity germanium (HPGe) radiation detectors for γ-ray spectroscopy.
• As a dopant or substrate material in advanced semiconductor research for exploring novel electronic properties.
• For fundamental research in nuclear physics, including studies of double-beta decay and neutrino physics.
• In the synthesis of specialized germanium-based alloys and compounds with tailored isotopic composition.
• As a reference standard in mass spectrometry and other analytical techniques requiring isotopically pure materials.

Quality Control

Our Germanium70 is produced and handled under stringent quality protocols to ensure isotopic and chemical purity meets the exacting standards of research and high-tech industries. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment levels, elemental impurities, and physical form. We adhere to relevant ISO guidelines and can support compliance documentation for specialized applications.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C) in a dry, clean environment. For long-term storage of high-purity material, an inert atmosphere (e.g., argon) is recommended to prevent surface oxidation.
